Problem 2:
Marcus measured in inches, Colton in centimeters. The same rock is being measured.
Centimeters are smaller than inches — so you need more of them to cover the same length.
That’s why Colton got a bigger number (13) even though it’s the same rock.
✔ Answer: Because centimeters are smaller units than inches, so you need more of them to measure the same thing.
